【摘要】 时间序列模式在很多领域中存在,时序模式的表示及存储查询是时间序列数据挖掘的重要任务之一。分析和研究了地震前兆时序模式的特点,采用半结构化语言XML并利用分段线性表示法表示地震前兆时序模式,在此基础上提出了针对Java、PL/SQL、命令行3种不同环境下地震前兆时序模式存储及查询方法,既保证了时序模式的存储查询效率,又满足了不同平台下针对时序模式的处理,从而进一步为地震预报服务。更多还原

【Abstract】 The Time Series pattern is a common data type in various scientific domains.The denotation and storage of time series is one of the important tasks in time series data mining.The characteristic of seismic portentous time series pattern is analysed.Using semi-structured language XML and precewise e linear representation to figure seismic portentous time series pattern.Three storage modes are proposed under the environments of Java,PL/SQL and command line which can query and match effectively for the purpose of earthquake prediction.更多还原
